Resumo O objetivo deste artigo é investigar
associação entre a proveniência de
lanches consumidos na
escola , seu
valor nutricional e o
sobrepeso /
obesidade . Estudo transversal com 3.930
escolares de 7-10 anos de idade, de Santa Catarina. O
consumo alimentar na
escola foi avaliado com R-24 horas ilustrado, e a origem dos
lanches por
entrevista estruturada.
Refrigerantes e
sucos artificiais, frituras, salgadinhos industrializados,
lanches prontos,
doces , guloseimas e
biscoitos recheados foram classificados como "
lanches de baixo
valor nutricional ", enquanto
frutas ,
sucos naturais,
legumes ,
verduras e
sopa de
verduras foram os "
lanches de alto
valor nutricional ". Realizou-se
regressão logística univariada e múltipla. O
sobrepeso /
obesidade se associou significativamente ao
consumo de alimentos provenientes da cantina (OR = 1,34; IC = 1,07-1,68), na rede particular. Trazer
alimentos de casa foi significativamente associado ao maior
consumo de
lanches de baixo
valor nutricional , nas
escolas públicas (OR = 1,56; IC = 1,32-1,83) e nas particulares (OR = 2,64; IC = 1,76-3,97). Os resultados apontam a necessidade de expansão de normativas que minimizem a disponibilidade de
alimentos de baixo
valor nutricional nas cantinas e que promovam
educação nutricional envolvendo a
comunidade escolar .
Abstract The scope of this article is to investigate the
association between the source of
snacks consumed in
schools , their
nutritional value and
overweight /
obesity . It involved a
cross-sectional study with 3,930 schoolchildren
aged between 7 and10 in the
state of Santa Catarina.
Food consumption in the
school was assessed with an illustrated 24-hour dietary recall and the source of
snacks was investigated by structured
interview .
Soft drinks and artificial fruit juices, fried and processed
snacks , ready-to-eat or sweetened
snacks , delicacies and stuffed biscuits were classified as "low
nutritional value foods ," while
fruit , natural fruit juices,
vegetables , and
vegetable soup were the "high
nutritional value foods ." Univariate and multiple
logistic regression was conducted.
Overweight /
obesity was significantly associated with higher
food consumption from the
school canteen (OR = 1.34; CI = 1.07-1.68) in private
schools . Bringing
food from home was significantly associated with increased
consumption of low nutritional
foods , both in public (OR = 1.56; CI = 1.32-1.83) and private (OR = 2.64; CI = 1.76-3.97)
schools . The results highlight the need for tightening of norms to reduce the availability of low
nutritional value food in canteens, and actions to promote nutritional
education involving the
school community .
